L. MORRIS SAFETY RAZOR Aug., 23, 1938.

-Filed'may 10, 1937 ATTORNEY9 Patentecl Aug. 23, 1938 UNITED STATES PATENT OFFICE Claims.

The invention relates to a safety razor and more especially to a rotary adjustable safety razor.

The primary object of the invention is the prof) vision of a razor of this Character, wherein the head of the razor is in the form of a circular body embraced by a sleeve, the latter having cut and bent therefrom Cutting blades, these being uniformly spaced from each other and each is adapted for shaving, the razor being of novel construction and is readily adjustable for the use of the Cutting edges in accordance with the condition of the same.

Another object of the invention is the provision of a razor of this Character, wherein the Cutting element is made from a blank of sheet steel bent into cylindrical form and having struck therefrom a series of Cutting edges, these being properly angled or disposed tangentially to the cylindrical formation and are usable singly for shaving purposes, the cylindrical element being readily acljustable for the selection of the indi- Vidual Cutting edge for use during shaving.

A further object of the invention is the provision of a razor of this Character, wherein the head thereof is formed with a gutther for the catching of spent lather and cut hairs during the use of the razor in shaving, the Cutting element of the razor being readily adjustable so that a selected Cutting edge can be brought into position for service at the will of the user of the razor and in this position will be held fixed, thus assuring extended service without danger of the Cutting of the person while shaving.

A further object of the nvention is the provision of a razor of this Character, which is extremely simple in construction, thoroughly reliable and effective in operation, assuring comfort to a user without liability of the Cutting of the skin during shaving, strong, durable, and'inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred` embodiment of the invention and pointed out in the claims hereunto appended.

50 In the accompanying drawing:

Figure 1 is a fragmentary perspective view of a razor constructed in accordance with the invention.

Figure 2 is a Vertical longitudinal sectional view through the head of the razor.

Figure 3 is a Vertical transverse sectional view thereof.

Figure 4 is a plan view of the blank from which the Cutting element of the razor is made.

Figure 5 is a side elevation of the head showing a protecting covering thereon.

Fgure 6 is a fragmentary sectional view on the line 6-6 of Figure 2.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the safety razor Constituting the present invention comprises a roller-like head or a circular body l which has centrally fitted therein at one end the axle stub II formed with and at right angles to the stem |2 .of a handle |3, the stub being held secure through the medium of a fastener or key M suitably fitting the head or body Hl and such stub so that the body or head will be prevented from rotation on this stub l I.

Encircling the head or body Ill is a longitudinally split sleeve-like cylinder |5 preferably made from a blank of sheet steel A normally flat and having cut and struck outwardy therefrom the series of Cutting edges |6, these being uniformly spaced from each other and are disposed longitudinally of the cylinder |5, they being disposed tangentially to the latter and are adapted for use singly in shaving. The cylinder |5 snugly embraces or clamps the head or body Ill and is inherently expansible and contractible for snug tight embracing action through Contraction thereof while on expansion the cylinder R5 can be loosened from the head or body for the turning thereof under adjustment of the same. In this manner a Cutting edge |6 can be selected for service in shaving.

The Cutting of the edges 16 and the angular disposition of the same with respect to the cylinder 15 provides next thereto slots I'I, the head or body IO being provided with a substantially V- shaped channel or groove |8 therein which is disposed longitudinally of the same to aford a catch trough for cut hairs or spent lather during the use of the razor and such cut hairs and lather will pass through the slot I'l in confronting relation to the trough |8 for depositin the latter.

The cylinder 15 next to the outer end thereof is formed with an instruck annular bead 19 fitting in a Companion seat or groove 20 in the head or body IB so that the said cylinder [5 when embracing the latter will be held against slippage longitudinally on said head or body.

The cylinder [5 at the other end has formed therein notches 2|, these aligning with the edges |6 and any one of the same is adapted to accommodate the stem 2 of the handle |3 when the bead |9 is engaged in the seat or groove 20 and thus in this manner the cylinder |5 is held against rotation or turning upon the head or body while one of the cutting edges |6 with its Companion slot aligns with the trough |8 in the said head or body so that this cutting edge IB in such alignment will be the active edge during shaving while the cut hair and spent lather will be deposited within the trough |8 during the use of the razor.

By the turning of the cylinder |5, any selected one of the cutting edges |6 may be brought into position for service in shaving.

In Figure of the drawing the cylinder |5 has exteriorly applied thereto a. protective covering 22 which is of cylindrical form and has provided therein overlying the edges |6 tearing sections 23 created by weakened lines 24, these having pull tab ends 25 beyond the outer end of the cylinder |5 so that on the tearing of a selected section 23 a cutting edge |6 of the cylinder 5 can be exposed for use, normally these cutting edges being covered and protected by the covering 22 when the razor is not in use. The stem |2 is provided with a slit 26 eifecting a flat contact 21 for the notches 2|, this being clearly shown in Figure 6 of the drawing, and thus there is no possibility that the cylinder |5 will turn on the body |0 when the razor is in use.

When it is desired that the cylinder |5 be adjusted to bring a cutting edge |6 into working position for cutting or shaving purposes, it is only necessary to press upon the notched end of said cylinder |5 causing the annular bead |9 to ride out of the channel or groove 20, the said cylinder |5 being longitudinally split and inherently expansible allows the n'ding of the bead out of the groove or channel so that the stem |2 becomes disengaged from a notch 2| in the said cylinder |5 and the latter now being free from locked engagement with the stem |2 may be turned on the body |0 to bring a selected cutting edge |6 into workable position. Thereafter the cylinder is shifted on the body IG to have the bead 9 ride into the channel or groove 2|] and also to bring the stem |2 into a notch 2| for the looking of the cylinder |5 on the said body |0.

The edges |6 are sufiiciently spaced arcuately from each other so that only one of these edges will be in cutting relationship with a user for the cutting of hair or shaving purposes. As it will be noted, the circular contour of this cylinder |5 protrudes these cutting edges |6 materially in different planes with respect to each other in their distributed relationship peripherally about the said cylinder so that but one edge IG is active at a time in the use of the razor and there is no liability of the inactive edges |6 cutting or injuring such user.

What is claimed is:

1. A razor of the character described comprising a roller-like head, a split expansible and contractible cylinder snugly embracing the said head and having outwardly extending cutting edges disposed tangentially to the said cylinder, a handle fixed to the head, and an end formed on the cylinder and engageable with the handle to hold the cylinder selectively adjusted against movement on the head.
